In APIs < 23 some things set in TextInputLayout's AccessibilityDelegate get overwritten, so announcements are not as expected.

Move to use native android:padding attrs instead of custom boxPadding attributes for text fields. This is accomplished by creating box styles for TextInputEditText, and setting android:padding attributes in those.
The TextInputLayout box styles set the appropriate TextInputEditText style on its child by wrapping the TextInputEditText style in theme overlays. This is kind of neat, since it allows for the user not to have to set a style on both the TextInputLayout and TextInputEditText - the user does not even have to know about the TextInputEditText styles with this pattern. It should also help clear up some confusion over where to set the hint and other areas of haziness between TextInputLayout and TextInputEditText.
The default editTextStyle is set to the filled box style, to match the default TextInputLayout style.
This change removes the box padding attributes, and it also removes the dimension resources in favor of setting them in the style to improve readability.
This commit also changes TextInputEditText constructors to both use a theme attribute in the 3-arg constructor and call through to the TextInputEditText overloaded constructors rather than call the super's constructor from each. This allows the theme attribute set in the theme overlays to take effect.
